Beckham says he never expected to be considered for the Euros this summer.
"I don't expect a call-up," he told the Mail on Sunday. "But there's a reason why I haven't retired from international football, that I've not said 'That's it', even at 37 years old. I always want to represent my country and I always want to be part of any England team.
"I doubt it will actually happen again. But there's always a chance. I'll never say never. I did bring my boots back with me!"
